To all whom z'z may concern:

Be it known that I, ALFRED C. SCHOEPFER, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have-invented a certain new and useful Improvement in Window Ventilators, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to window ventilators and the object of the invention is to provide a window ventilator adapted to direct the currents of air upwardly into the room so that a draught is not caused about the occupants of. the room. Another object of the invention is to provide a window ventilator adapted to be adjusted at dierent angles to the window frame to admit more or less air. Al further object of the invention is to provide a window ventilator of the character described in which the space between the ventilator and window frame at each end is closed so that the air may only enter through the top of the ventilator. A still further object of the invention is to provide a window ventilator in which the lower edge is positioned in close proximity with the window sill at any adjustment thus preventing rain, sleet or snow from passing between the lower edge of the ventilator and window sill. These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred orm of construction by which these objects are attained is shown in the accompanying drawings in which- Fig. 1 is a side elevation of a window ventilator embodying my invention.

Fig. 2 is a front view thereof.

Fig. 3 is an enlarged section taken on line 3--3 of Fig. 1.

Fig. 4 is an enlarged view-of one of the pivot screws.

As shown in Figs. 1 and 2, a bracket 1 is secured to the window frame 2 by screws 3. Formed integrally with the member 1 is a round lug f1 from which an angularly bent endV or foot 5 extends adapted to be secured to the window sill 6 by screws 7 One of these brackets is provided on each side of the window frame. As shown in Fig. 2, a channel shaped frame member 8 is providedon each side of the window frame adapted to receive a glassdeflector 94 l and the frame member 8 is provided with a lower rounded end 10 similar to the lugl of the bracket 1 which is provided with an aperture 11 adapted to receive the round portion 120i a screw 13, as shown in Fig.-

4. The'end 14 of the screw is of smaller diameter than the portion 12 and is adapted to be threaded into a threaded aperture provided therefor in the lug 4: of the bracket 1. This pivots the frame 8 on the bracket 1 and allows turning of the deflector to admit more or less air. To prevent draughts from passing between the window frame and theframe 8 when the ventilator is open, I provide a member 15 which' is made of water-proof material such as leather, imitation leather or rubberized cloth and is folded similar to a bellowsto allow the frame 8 and deilector 9 to be adjusted. To secure the frame 8 at different' angles'to the bracket 1 I provide an arcuate arm 16 which is secured to the bracket 1 andwhich extends beneath a U shaped bracket 17 which is secured to the frame 8. A set screw 18 is threaded through the bracketfl? and is provided with a knurled knob 19 by which the set screw may be tightened to bindingly secure the frame 8 at any adjustment on the arm 16.

In operation the bracket 1 is secured to the window frame 2 by screws 3 the lower end 5 being secured to the window sill 6 by thek screw 7. When the device has been correctly mounted on the interior of the window frame the screws 18 are loosened by turning the knurled heads 19 and the delector 9 is adjusted to the desired position at which time thescrews 18 are again tightened by turning the knurled heads 19 to bind the delector in position. At this time the lower sash is raised to admit air to the ventilator the air passing between the lower edge of the sash and sill thence into-the ventilator, the delector 9 causing` the air to be directed upwardly so as to prevent draughts about the occupants of the room and at the same time provide proper ventilation. In order c to direct the air upwardly the lower edge of the sash should not be positioned above the upperjend of the brackets 1. When the sash is opened above the ventilator the air will flow directly into the roo-m over the| ventilator thus causing an undesirable draught about the occupants of the roo-m. It can `thus be seen that the amount of air entering the room may be regulated by the opening of the sash and by positioning of the deector to vary the opening of the ventilator. It will also benoted that the folded members l at each end of the ventilator prevent the air from passing between the frame 8 and adjacent window frames which would also cause undesirable draughts and if the members were not provided rain or snow might enter the room through the open spaces between the window frame and frames 8.

A feature of this invention is in the arrangement of the glass deflector to extend to close proximity to the window sill below the pivot point in order that rain, wind and snow may not pass freely below the lower edge of the detlector and the sill of the window. This is accomplished by providing each channel member with an offset lower end to engage over the outside of the portion 4 of its bracket and the deflector which rests in the channel is cut out at this point and extends inside of the member 4: to close proximity with the sill 6 being just Sulliciently spaced therefrom to allow the de- Hector to be adjusted toward or from the vertical portion of the window frame.

From the foregoing description it becomes evident that the device is very simple and efficient in operation, will not easily get out or' order, is of strong construction and low manufacturing cost and provides a device which accomplishes. the objects described.

Having thus fully described my inven tion, its utility and mode of operation, what I Iclaim and desire to secure by Letters Patent of the United States isl. ln a ventilator, brackets adapted to be secured to each vertical side of a window frame on the the interior thereof, each having a lug adjacent the sill end, a channel member for each bracket, each being oii'set at the lower end to provide a foot to engage over the outside of the lug ofl the respective bracket, means for securing the said o'set lower end and lug in pivotal relation, a fo1d able fabric member connecting each channel with its respective bracket, and a glass deector member engaging in the channel members at each end and having the lower portion of the said edge notched to extend about the bracket permitting the lower edge of the glass to lie in close proximity to the sill below the said pivot points.

2. In a window ventilator, brackets adapted to be Secured to each vertical side of a window frame and having a foot supported on the sill, an apertured lug formed between the frame and sill portions of each bracket, a channel member for each bracket, a glass deflector member having ends supported in each channel, the structure being such that a recess is provided between the lower end of each channel member and the glass to receive the apertured lug of the bracket, a pin for securing the lower end of each channel to the respective lug, and a plaited fabric extending between each channel member and the vertical portion of the respective bracket.

3. In a window ventilator, brackets having a portion for attachment t-o each vertical side of a window frame and a foot portion attachable to the window sill, a lug formed between the fra-me and sill portions of each bracket, a channeled member, one for each bracket, terminating in an apertured lower end to engage the lug of the respective bracket, a pivot member for each channel member secured to eachlug, means for adjusting the channel members about the pivot, a plaited fabric extending between each channel member and the vertical portion of the respective bracket, and al glass defiector member supported atV each end in the respective channel members and extending below the pvot point of the bracket.

In testimony whereof, I sign this specilication.

ALFRED C. scHoEPFER.
